We discussed this internally and came to the conclusion that we don't
want to spread the usage of this binding that is currently used for the
barebox environment as well.

Instead we want to go into another direction:

The MBR/GPT partitions should be described in a node under the physical
device and then the state node can continue using the phandle only, so
something like:

backend = <&state_part>;

&mmc {
	partitions {
		compatible = "gpr-partitions";

		state_part {
			partuuid = "16367da7-c518-499f-9aad-e1f366692365"
		};
	};
};
